Thailand’s statutory annual leave is among the leaner minimums in Southeast Asia: six working days a year, available only after twelve continuous months of service. Most employers operating in Bangkok, Chiang Mai, and the Eastern Economic Corridor sit well above that line — ten to fifteen days is the practical norm — but the legal floor is what governs disputes, audits, and termination payouts.
This guide walks through the rules in section 30 of the Labour Protection Act B.E. 2541 (1998), the one-year service rule that gates eligibility, how employers are expected to schedule leave through their work rules, and the pitfalls Thai employers most often run into.
Key takeaways
- The Labour Protection Act mandates at least six working days of paid annual leave per year for employees who have completed one year of continuous service.
- Annual leave is paid at the employee’s normal wage rate — pay cannot be deducted for statutory leave days taken within the entitlement.
- The specific number of leave days (minimum six) and the leave year are set by the employer’s work rules, which must be registered with the Department of Labour Protection and Welfare.
- The employer schedules annual leave or agrees the dates with the employee, and must allow leave to be taken within the leave year.
- Thailand’s 13 statutory public holidays are separate from annual leave and do not count toward the six-day minimum.
The statutory minimum: six working days
Section 30 of the Labour Protection Act B.E. 2541 (1998) sets the floor for paid annual leave. Once an employee has worked continuously for at least one year, the employer must grant at least six working days of paid annual leave per year. Employers may set a higher number of leave days in their work rules — and in practice, many do.
The actual entitlement an employee receives is whatever number is recorded in the employer’s work rules, provided it is not less than six. The Department of Labour Protection and Welfare’s published guidance treats six days as a floor, not a recommendation. Many Thai employers offer ten to fifteen days as a standard benefit, particularly in professional services, manufacturing with foreign ownership, and the technology sector.
For comparison, this is significantly less generous than the Singapore floor of seven days rising to fourteen, the Australian entitlement of four weeks under the National Employment Standards, or the UK statutory minimum of 5.6 weeks. When you draft a Thai contract, benchmark against the local market — applying the six-day minimum alone will look stingy to most professional candidates.
Eligibility and the one-year service rule
Two questions decide whether an employee gets statutory annual leave: are they covered by the Labour Protection Act, and have they completed one year of continuous service?
Coverage under the Labour Protection Act
The Labour Protection Act applies to most employees working under an employment contract in Thailand, regardless of nationality, role seniority, or whether they are paid monthly or daily. Coverage is not contingent on the employer’s size or industry in the way some other jurisdictions handle it.
The one-year continuous service rule
The headline difference between Thailand and many other APAC jurisdictions is the eligibility threshold. Annual leave does not accrue from day one in the way it does under the Singapore Employment Act or the Australian National Employment Standards. Instead:
- An employee with less than one year of continuous service has no statutory entitlement to paid annual leave. The employer may grant leave at their discretion, but is not required to.
- Once an employee completes twelve months of continuous service, the full statutory entitlement of at least six working days applies for that year.
- Service must be continuous — breaks in employment reset the clock unless the work rules or contract say otherwise.
Many employers narrow this gap voluntarily by granting pro-rated leave from a probation pass date, six months in, or other earlier milestones. That is a contractual benefit, not a statutory one — but once it is written into the work rules, it becomes binding.
Annual leave pay
The Labour Protection Act requires annual leave to be paid at the employee’s normal wage rate. Pay cannot be deducted for annual leave days taken within the statutory entitlement. The calculation is based on the employee’s daily wage rate — for monthly-paid employees, this is the monthly salary divided by the number of working days in the relevant period under the work rules.
For employees on a fixed monthly salary, this is mechanical: salary continues uninterrupted during a leave day, and the payslip should not show a deduction. For daily-rated or piece-rated employees, the employer must pay the equivalent daily wage for each statutory leave day taken.
Getting the wage rate wrong on annual leave is a common payroll error in Thailand, particularly when employers pay variable allowances alongside a base wage. The cleanest test is the wage the employee would have received for working a normal day at the same role, without overtime or one-off premiums.
Employer obligations under section 30
Thai employers covered by the Labour Protection Act have five core obligations on annual leave:
- Grant at least six working days of paid annual leave per year to employees who have completed one year of continuous service.
- Pay wages during annual leave at the employee’s normal rate, with no deduction for leave days taken within the entitlement.
- Determine the specific number of leave days (at or above the six-day minimum) and the leave year in the work rules, registered with the Department of Labour Protection and Welfare.
- Allow the employee to take annual leave within the leave year — leave must actually be available, not blocked indefinitely by operational pressure.
- Schedule the leave or agree the dates with the employee — the employer is empowered to fix the dates, but in practice most workplaces operate by mutual agreement.
The third obligation is often overlooked by smaller employers and by foreign companies setting up a Thai subsidiary. The leave year and the number of leave days must both appear in the registered work rules; without that, the default minimum applies and any employer claim of a different leave year is hard to defend.
What employees are entitled to
The corresponding rights for employees are straightforward:
- Right to at least six working days of paid annual leave after one year of continuous service.
- Right to be paid at the normal wage rate during annual leave, without deduction for those days.
- Right to take annual leave as determined by the employer’s work rules — leave that exists on paper must also exist in practice.
Unused annual leave can be carried forward to the next year if the employer’s work rules allow it. On termination, unused annual leave is typically paid out, but the precise treatment depends on the employer’s policy as recorded in the work rules. Where the work rules are silent, accrued statutory leave is generally treated as a payable entitlement.
Common pitfalls
Thai employers — particularly multinationals applying a global leave policy without local adjustment — tend to fall into the same three traps:
1. Confusing the statutory minimum with typical entitlement
Six days is a floor, not a guideline. Offering six days to a Thai software engineer or a finance professional in Bangkok will lose you the candidate. Many Thai employers offer ten to fifteen days of annual leave as standard. Benchmark against your industry, not the statute.
2. Not specifying the leave year in the work rules
Employers must define the leave year in their registered work rules. Companies that rely on an unwritten “calendar year” or “anniversary year” practice run into trouble at audits and at termination. Without a documented leave year, calculations of accrual, carry-over, and payout become contested.
3. Not allowing employees to take their leave
Granting six days on paper is not enough. Employers must allow leave to be taken within the leave year. A pattern of refusing leave requests because “it’s a busy quarter” is a breach of the Act, and accumulated unused leave that the employee was prevented from taking is a frequent source of termination disputes.

Frequently asked questions
How many days of annual leave do Thai employees get?
The Labour Protection Act sets a statutory minimum of six working days per year for employees who have completed one year of continuous service. The actual number of leave days is determined by the employer’s work rules and may be higher than six. Many Thai employers offer ten to fifteen days as a standard benefit.
Do I get annual leave in my first year in Thailand?
The Labour Protection Act requires one year of continuous service before paid annual leave becomes a statutory right. For employees with less than one year of service, the employer may grant leave at their discretion, but is not required to. Many employers voluntarily grant pro-rated leave earlier through their work rules.
Can employers offer more than six days of annual leave?
Yes. The six-day minimum is the statutory requirement. Many employers offer ten to fifteen days or more as a standard benefit, particularly in professional services, technology, and multinational companies. Once a higher number is written into the work rules, it becomes contractually binding.
Are part-time employees entitled to annual leave?
Yes, part-time employees are entitled to annual leave if they meet the one-year continuous service requirement. The entitlement under the Act is the same as for full-time employees, although the work rules may specify how the wage rate is calculated for less-than-full-time schedules.
Does annual leave include public holidays?
No. Thailand has 13 statutory public holidays, which are separate from annual leave and do not count toward the six-day statutory minimum.
What rate of pay applies during annual leave?
Annual leave is paid at the employee’s normal wage rate. Pay cannot be deducted for annual leave days taken within the statutory entitlement. For monthly-paid staff, salary continues uninterrupted; for daily-rated staff, the normal daily wage applies.
Putting it into practice
If you employ staff in Thailand, the practical to-do list is short:
- Confirm your work rules state annual leave entitlement and the leave year clearly, ideally above the six-day floor.
- Register the work rules with the Department of Labour Protection and Welfare.
- Track continuous service so the six-day entitlement starts on the correct anniversary date.
- Verify your payroll system does not deduct wages for statutory leave days taken.
- Make sure leave is genuinely available within the leave year — granting it on paper is not enough.
A modern leave management system handles continuous service tracking, work-rule-based leave years, and statutory minimum enforcement automatically — so the next time someone hits their one-year anniversary in Bangkok, the six-day entitlement appears in the right balance without anyone having to reread the Labour Protection Act.
